System for utilizing carbon dioxide of flue gas captured by cold heat of liquefied natural gas

A system for utilizing carbon dioxide of a flue gas captured by cold heat of liquefied natural gas (LNG), the system comprising:

• a mining-site apparatus including a mining apparatus for mining natural gas and further including a liquefier for liquefying the mined natural gas into the LNG, the mining apparatus configured to drill in an oil field from which the natural gas is extracted and to replace the extracted natural gas by injecting a filler into the oil field:
• a transportation vehicle for transporting the LNG;
• and
• a consumer-site apparatus including
• a power generator configured to generate electricity and produce the flue gas,
• an LNG storage configured to store the LNG transported by the transportation vehicle, and
• a regasification and capture apparatus configured to regasify the LNG transported by the transportation vehicle and to capture dry ice from the carbon dioxide of the flue gas by receiving the flue gas from the power generator and perform a heat exchange between the LNG stored in the LNG storage and the flue gas produced by the power generator,
• wherein the power generator generates the electricity by using the natural gas obtained by regasifying the LNG at the regasification and capture apparatus,
• wherein, in the regasification and capture apparatus, the flue gas produced in the power generator exchanges heat with the LNG such that the LNG is regasified at an increased temperature and such that the dry ice is captured from the carbon dioxide contained in the flue gas,
• wherein the transportation vehicle transports the captured dry ice to the mining-site apparatus, and
• wherein the mining apparatus injects the carbon dioxide, as the filler, that forms the dry ice transported by the transportation vehicle to mine the natural gas.

A system for utilizing carbon dioxide of a flue gas captured by cold heat of liquefied natural gas (LNG), the system comprising:

• a plurality of mining-site apparatuses, each for mining at least one of natural gas and crude oil;
• a plurality of transportation vehicles, each for transporting the LNG obtained by liquefying the natural gas mined in at least one of the mining-site apparatuses;
• and
• a plurality of consumer-site apparatuses, each for regasifying the transported LNG,
• wherein each mining-site apparatus includes a mining apparatus for mining natural gas, and a liquefier for liquefying the mined natural gas into the LNG, the mining apparatus configured to drill in an oil field from which the natural gas is extracted and to replace the extracted natural gas by injecting a filler into the oil field,
• wherein each consumer-site apparatus includes
• a power generator configured to generate electricity and produce the flue gas,
• an LNG storage configured to store the LNG transported by the transportation vehicle, and
• a regasification and capture apparatus configured to regasify the LNG transported by the transportation vehicle and to capture dry ice from the carbon dioxide of the flue gas by receiving the flue gas from the power generator and perform a heat exchange between the LNG stored in the LNG storage and the flue gas produced by the power generator,
• wherein the power generator generates the electricity by using the natural gas obtained by regasifying the LNG in the regasification and capture apparatus,
• wherein, in the regasification and capture apparatus, the flue gas produced in the power generator exchanges heat with the LNG such that the LNG is regasified at an increased temperature and such that the dry ice is captured from the carbon dioxide contained in the flue gas,
• wherein the transportation vehicle transports the captured dry ice to at least one of the plurality of mining-site apparatuses, and
• wherein the mining apparatus injects the carbon dioxide, as the filler, that forms the dry ice transported by the transportation vehicle to mine the natural gas.
